Abstract

To provide an electric vacuum cleaning apparatus and a cleaning head can continuously perform both of suction cleaning and wiping for disinfecting the surface to be cleaned together. The apparatus includes: an electric blower that generates suction vacuum pressure; a suction air passage equipped with a suction port and fluidly connected to a suction side of the electric blower; an electrolyzed-water generator that electrolyzes water to produce electrolyzed water containing hypochlorous acid; a wiping-member attachment to which a wiping member is detachably attached; and a supply mechanism that supplies the electrolyzed water to at least one of a surface to be cleaned and the wiping member that is attached to the wiping-member attachment.

Claims (33)

1. An electric vacuum cleaning apparatus comprising:

an electric blower that generates suction vacuum pressure;

a suction air passage equipped with a suction port and fluidly connected to a suction side of the electric blower;

an electrolyzed-water generator that electrolyzes water to produce electrolyzed water containing hypochlorous acid;

a wiping-member attachment to which a wiping member is detachably attached, the wiping-member attachment being displaced from the suction port in forward and backward directions;

a supply mechanism that supplies the electrolyzed water to a surface to be cleaned; and

a rotatable brush arranged in the suction port to be shifted in the forward and backward directions with respect to the wiping member, wherein

the supply mechanism is configured to

supply the electrolyzed water to part of the surface to be cleaned sandwiched between the suction port and the wiping member attached to the wiping-member attachment,

at a time of moving in the forward direction in which the suction port and the rotatable brush move ahead of the wiping member, supply the electrolyzed water to the surface to be cleaned so that the wiping member wipes off the electrolyzed water on the surface, and

at a time of moving in the backward direction in which the wiping member moves ahead of the suction port and the rotatable brush, shut off supply of the electrolyzed water to the surface to be cleaned.

2. The electric vacuum cleaning apparatus according to claim 1 , further comprising a wiper that is disposed between the suction port and a supply area of the electrolyzed water from the supply mechanism to the surface to be cleaned and can wipe off the electrolyzed water.

3. The electric vacuum cleaning apparatus according to claim 2 , further comprising a shield disposed between the suction port and a supply area of the electrolyzed water from the supply mechanism to the surface to be cleaned,

wherein the shield prevents the electrolyzed water, which is supplied to the supply area in at least a part of space between the suction port and the supply area, from sucking to the suction port by being in contact with the surface to be cleaned.

4. The electric vacuum cleaning apparatus according to claim 3 , further comprising a moisture absorber that is provided in the suction air passage and absorbs the electrolyzed water sucked into the suction air passage due to the suction vacuum pressure.

5. The electric vacuum cleaning apparatus according to claim 2 , further comprising a moisture absorber that is provided in the suction air passage and absorbs the electrolyzed water sucked into the suction air passage due to the suction vacuum pressure.

6. The electric vacuum cleaning apparatus according to claim 2 ,

wherein the supply mechanism supplies the electrolyzed water to both of the surface to be cleaned and the wiping member.

7. The electric vacuum cleaning apparatus according to claim 2 , further comprising an input unit configured to receive an operation of switching whether to permit supply of the electrolyzed water in the supply mechanism.

8. The electric vacuum cleaning apparatus according to claim 1 , further comprising a shield disposed between the suction port and a supply area of the electrolyzed water from the supply mechanism to the surface to be cleaned,

wherein the shield prevents the electrolyzed water, which is supplied to the supply area in at least a part of space between the suction port and the supply area, from sucking to the suction port by being in contact with the surface to be cleaned.

9. The electric vacuum cleaning apparatus according to claim 8 , further comprising a moisture absorber that is provided in the suction air passage and absorbs the electrolyzed water sucked into the suction air passage due to the suction vacuum pressure.

10. The electric vacuum cleaning apparatus according to claim 8 ,

wherein the supply mechanism supplies the electrolyzed water to both of the surface to be cleaned and the wiping member.

11. The electric vacuum cleaning apparatus according to claim 8 , further comprising an input unit configured to receive an operation of switching whether to permit supply of the electrolyzed water in the supply mechanism.

12. The electric vacuum cleaning apparatus according to claim 1 , further comprising a moisture absorber that is provided in the suction air passage and absorbs the electrolyzed water sucked into the suction air passage due to the suction vacuum pressure.

13. The electric vacuum cleaning apparatus according to claim 12 ,

wherein the supply mechanism supplies the electrolyzed water to both of the surface to be cleaned and the wiping member.

14. The electric vacuum cleaning apparatus according to claim 12 , further comprising an input unit configured to receive an operation of switching whether to permit supply of the electrolyzed water in the supply mechanism.

15. The electric vacuum cleaning apparatus according to claim 1 ,

wherein the supply mechanism supplies the electrolyzed water to both of the surface to be cleaned and the wiping member.

16. The electric vacuum cleaning apparatus according to claim 15 , further comprising an input unit configured to receive an operation of switching whether to permit supply of the electrolyzed water in the supply mechanism.

17. The electric vacuum cleaning apparatus according to claim 1 , further comprising an input unit configured to receive an operation of switching whether to permit supply of the electrolyzed water in the supply mechanism.
